We can modify the dots and to see a geometric sequence representation.
The gray dot allow us to modify the ordinate axe scale.
The dots in the Y-axe forms a geometric sequence and the dots in the X-axe forms an aritmetic trivial sequence.
When the ratio r is grater than 1 we have a increasing sequence.
If the ratio is less than 1 the sequence is decreasing and the general term tends to 0.
If we see the sequence as a function, its domain is the natural numbers. We can easily extends this domain to be
the integers. We want to extends this function to the rationals and to the reals numbers.
